Answer:
(B) A selected group of participants that is representative of a larger population
Step-by-step explanation:
A sample statistic is a piece of information that you get from a fraction of the population. This information is representative of a larger population.
For example, someone wants to conduct a survey about the most popular NFL team in Syracuse, NY, if it is the Buffalo Bills or the New York Giants. This person is not going to ask each person for whom they cheer. They are going to collect data from a fraction of the population and this data will be expanded to include the entire population.
So, the correct answer is:
(B) A selected group of participants that is representative of a larger population
Answer:
icecream = $2.99
donut = $1.19
creamcake = $4.99
Step-by-step explanation:
The picture shows $7.17 for 2 x ice-cream and 1 donut
We are given 3 cream cakes that total 14.97 we divide by 3 = 4.99
9.17- 4.99=4.18
=5.37-4.18 =1.19
we can then fill out the boxes.
1.19 +1.19 = 2.38 = 5.37-2.38= £2.99
2.99 +2.99 +1.19 = $7.17
We can see total first two rows = $12.56
2.99+2.99+2.99 +1.19 +1.19+1.19 = $12.56
You have to multiply your 20cm by 6cm and your final answer being 120 because 0 times 6 is zero and 2 times 6 is 12, then that getting you 120
-24a²- 6a +9 = - 3(8a² +6a - 9)
8a² +6a - 9 =0
x=(-b +/-√(b² - 4ac))/2a
x = (-6 +/-√(36+4*8*9) /(2*8) = (-6 +/-√(324) /16 = (-6 +/-18)/16
x1 = (-6 +18)/16 = 0.75
x2 = (-6 -18)/16 = - 1.5
-24a²- 6a +9 = - 3(8a² +6a - 9) = -3(a - 0.75)(a + 1.5)
So all you have to do is take the first numbers of each multiple and multiply them.
1 x 2 x 3 x 4 = 24
Now you just add the 4 zeros to your answer.
240,000
Our answer even checks!
10 x 20 x 30 x 40 = 240,000
Good Luck! :)
